Classify physical quantities into scalars or vectors. In National 5 Physics learn how add two vectors to find their resultant.

Practise using vector components when adding, subtracting or calculating the magnitude of vectors ahead of your National 5 Maths exam.

Abstract This paper provides derivation of some basic identities for complex four-component vectors defined in a complex four-dimensional spacetime frame specified by an imaginary temporal axis. The ...

Vectors have units, if you leave them off you are probably a mathematician (just kidding). Also, this notation can be expanded to three dimensions by adding a z-hat or k-hat component.

So our vector has a horizontal component of 4.33 and a vertical component of 2.5. In what's known as unit vector notation, we'd describe this vector as v = 4.33i + 2.5j.
